ACPI changes for adding an i2c device (microchip switch) on intel adlink atom board

simonkbaby — Wed, 28 Jun 2023 06:03:27 GMT

Hello,

I am adding a device on intel adlink processor board via i2c interface. The device added is mirochip ksz9897 switch. I have enabled all the kernel DSA flags for this device (CONFIG_NET_DSA_MICROCHIP_KSZ9477, CONFIG_NET_DSA_MICROCHIP_KSZ_COMMON, etc). I would like to know the device tree changes for invoking the correct driver function. I know intel uses ACPI tables for device tree mappings. DO we have any meta layer in yocto for adding and updating ACPI tables?

Regards

Simon
